Reproduction

@Data
public class JacksonModel {
    private String code;
    private List<JacksonData> data;

    @Data
    public static class JacksonData {
        private Long id;
        @JsonProperty("mValue")
        private List<JacksonVal> mValue;
    }

    @Data
    public static class JacksonVal {
        private String k;
        private Integer v;
    }
}

public static void main(String[] args) throws Exception {
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);

        String json = "{\"code\":\"success\",\"data\":[{\"id\":224570001,\"mValue\":[{\"k\":\"2023-07-22\",\"v\":100},{\"k\":\"2023-07-23\",\"v\":200}]}]}";
        System.out.println(json);

        JacksonModel result0 = objectMapper.readValue(json, JacksonModel.class);
        json = objectMapper.writeValueAsString(result0);
        System.out.println(json);

        result0 = objectMapper.readValue(json, JacksonModel.class);
        json = objectMapper.writeValueAsString(result0);
        System.out.println(json);
    }

Please make a test case that does not use lombok. This is likely a lombok-related problem.
